To all whom, it may concern.-

Be it known that I, \VALTER Fnosr, a subject of the Queen of GreatBritain, residing at London, England, haveinvented new and usefulImprovements in Apparatus for Raising and Lowering the \Vindows ofRailway and other Carriages, of which the following is a specification.

This invention relates to improvements in apparatus for raising andlowering the sliding windows of railway and other carriages, the objectof the invention being the production of an apparatus whereby the sashescan be easily and quickly opened and closed by merely operating by thehand a handle or knob on the inside of the carriage door or window.

In carrying outmy invention the sash-frame carrying the glass is made tofreely run up and down in grooves or guides, as usual, and the said sashframe is counterbalanced by a spring or weight. Along the bottom of thesash-frame is a slot, in which runs a small wheel or runnerblock. Thesaid wheel or runner-b1ock is attached to the end of a radiating lever,jointed at the other end to the side of the sash-box, and at a shortdistance from this joint there is jointed on the radiating lever a link,which is connected at the other end to a crank fixed rigidly on thespindle of the knob or handle in such a manner that when the handle orknob having the crank is turned it communicates a motion to theradiating lever by means of the link, and by means of the radiatinglever a raising or lowering motion is given to the sash-frame, accordingto the direction in which the handle is turned.

I sometimes employ in connection with the said apparatus a ratchetarrangement consisting of two ratchet-wheels attached to the spindle ofthe handle, the said ratchetwheels having their teeth formed in oppositedirections. The crank on the handle works frictionwise with one of theratchet-wheels, which allows of the window being lowered by the pressureof the hand without using the handle. The other wheel is rigidly fixedto the handlespindle, and in the teeth of the said ratchetwheels works acompound-spring ratchet. The main part of the ratchet takes into thewheel which works frictionwise with the crank, and the other part of theratchet takes into the ratchet-Wheel fixed rigidly on the spindle of thehandle. These ratchets operate in such a manner that when the handle isturned to the right hand the ratchet-wheels revolve and allow the mainratchet to fall successively into the teeth of its ratchet-wheel untilthe sash-frame is raised to its desired position, when the handle willbe prevented from turning any farther. By turning the handle to the lefthand the ratchet-wheel fixed rigidly on the handle-spindle is firstmoved the distance of the length of a tooth in the wheels, theratchetwheel fixed on the handle-spindle having a pin which works in aslot in the ratchet-wheel which is loose on the handlespindle, whicharrangement allows of the said motion, and by this motion the mainratchet is raised out of its ratchet-wheel by the second part of theratchet acting on apin in the main ratchet, thus allowing thesash-frame. to be lowered tooth by tooth until the turning of the handlestops, and by this arrangement the window can be maintained at anyrequired position or height.

In order to enable my invention to be fully understood, I will proceedto describe the same by reference to the accompanying drawings, inwhich- Figure 1 represents an elevation of the outer side of a railwayor other carriage door, showing my improved apparatus for raising andlowering the window of the same applied thereto. In this view part ofthe frame of the door is removed to more clearly illustrate myinvention, and the window is shown in its raised or closed position.Fig. 2 is a vertical transverse section of the same on line A B ofFig. 1. Fig. 3 is a similar view to Fig. 1, but showing the window inits lowered or open position. Figs. 4, 5, and 6 are similar views toFigs. 1, 2, and 3, but showing the improved apparatus provided with anarrangement of ratchetwheels to admit of the window being lowered by thepressure of the hand alone when required. Figs. 7, 8, and 9 are detachedviews drawn to a larger scale, showing the arrangement of the ratchetwheels.

Similar letters in all the figures represent similar parts.

I will first describe my invention by reference to Figs. 1 to 3.

q is the sash-frame of the window, made to freely run up and down in thegrooves or guides b, in the frame of the door 0 (or of the window) inthe usual manner.

y is a barrel containing a coil-spring for counterbalancing the weightof the sash frame; or a weight may be employed for this purpose.

e is the slot at the bottom of the sash-frame a, and f is the smallwheel, roller, or runnerblock, which runs in the slot e.

g is the radiating lever, to one end of which the roller f is attached,the other end being jointed at h to the side of the sash-box t.

'j is the link, jointed at k to the radiating lever g, and Z is thecrank on the spindle m of the knob or handle a, to which crank l theother end of the linkj is jointed, as shown.

2 is a tape or band, of metalorother suitable material, which passesround the barrel yand is attached to the radiating lever y, and which iswound on the said barrel by means of the coil-spring hereinbeforedescribed, so as to assist in raising the window.

To raise the window, the parts being in the position shown in Fig. 9,the handle it is turned toward the right-hand side, whereby the crank Zwill raise the link j and radiating lever 9, thereby raising the sashframe a, which will remain in any position to which it may be raised orlowered by being counterweighted by the coil-spring, which operates thebarrel 3 and winds the tape or band z thereon and assists in raising theradiating lever g. To lower the window, the handle nis simply turned'inthe opposite direction, and the operation of the parts will be wellunderstood without further description. If required, the crank 1 mayhave notches or teeth out in its circular portion and a springlocking-piece taking into these teeth in such a manner that it can beunlocked on turning the handle in either direction.

In the arrangement shown in Figs. 4 to 9, in which the ratchetarrangement is employed, a spiral spring, d, is shown forcounterbalancing the weight of the window, the said spring beingattached to the door-frame c and to the link j.

0 and p are the two ratchet-wheels, having their teeth formed inopposite directions, as shown clearly in elevation at Figs. 7 and 8, andin section at Fig. 9. The ratchet-wheel o is loose upon thehandle-spindle m, and works frictionwise with the crank Z by means of aspring-plate, g, riveted or otherwise suitably fixed to theratchet-wheel 0, and bearing upon the surface of the boss 1' of thecrank, as shown in Fig. 9. The ratchet-wheel ois provided with a boss,s, upon which the boss 1 of the crank can rotate when thewindow islowered by the pressure of the hand without using the handle n. When,however, the

window is raised or lowered by means of the.

handle at, the boss of the crank is by means of the said friction forcedto rotate with the ratchet-wheel 0, as hereinafter described. The" otherratchet-wheel, p, is rigidly fixed to the handle-spindle 1n.

t' and u represent the compound -spring ratchet. the ratchet-wheel 0,and the other part,u,piv oted to the main part t, takes into thematchet-wheel p.

The main part, t, thereof takes into v is the pin on the ratchet-wheelp, and w: is the slot in the ratchet-wheel o, in which 'slot the pin 1)works, and by means of which To raise the window, the"parts being in theposition shown in Fig. 6, thehandlen is turned toward the right hand inthe direction indicated by the arrow in Fig. 7, when the mainratchet t,as the ratchet-wheels o and p revolve, will fall successively into theteeth of its ratchet-wheel 0, and the part a of the compound ratchetwill pivot on the main ratchet t, and will pass over the teeth of itsratchet p. The ratchet-wheels as they revolve will carry with them thecrank Z, which, by means of the link j, will cause the radiatinglevergto raise the window, the rollerf meanwhile sliding in:

its slot e until the window is closed, when the handle will be preventedfrom turning any farther, or until the window is raised to any otherrequired position or height, at which position or height it will bemaintained. To lower the window, the handle 1:. is turned to? ward theleft-hand side in the direction indicated by the arrow in Fig. 8, whenthe main.

ratchet will be moved out of the teeth of its ratchet-wheel 0 in themanner hereinbefore described, and shown in the said Fig. 8, and

both ratchet-wheels will be free to rotate, andwill carry with them thecrank 1' until the window has been lowered to the required potion bymeans of the link j and lever g, whenthe handle n is released andthewindow will be maintained in the said position.

If the window be pressed by the hand in order to lower the same, theratchet-wheels will be prevented from moving by means of V the compoundratchet, and the boss r of the crank will be forced by the windowoperating the link j and lever g to move frictionwise over the ratchet0.

Having now described the nature of the said invention and in what mannerthe same is to I be performed, what I claim is- 1. In apparatus forraising and lowering the windows of railway and other carriages, thecombination of a radiating leverjointed at one end to the frame of thedoor or window, and having its other end sliding in a slot in thesash-frame,with a link and crank,substantially as and for the purposeshereinbefore described.

2. In apparatus for raising and lowering the windows of railway andother carriages,-the combination of a radiatingleverjointed at one endto the frame of the door or window, and having its other end sliding ina slot in the sash-frame, with a link, and a crank rigidly fixed on thespindle of a handle working in the frame of the carriage door or windowand a counterbalanoing-spring, (or a weight,) all arranged substantiallyas and for the purposes hereinbefore described,and represented in theaccompanying drawings.
